Properties for the MDIO bus multiplexer/glue of Amlogic G12a SoC family.

This is a special case of a MDIO bus multiplexer. It allows to choose between

the internal mdio bus leading to the embedded 10/100 PHY or the external

MDIO bus.

Required properties in addition to the generic multiplexer properties:

- compatible : amlogic,g12a-mdio-mux

- reg: physical address and length of the multiplexer/glue registers

- clocks: list of clock phandle, one for each entry clock-names.

- clock-names: should contain the following:

  * "pclk"   : peripheral clock.

  * "clkin0" : platform crytal

  * "clkin1" : SoC 50MHz MPLL

Example :

mdio_mux: mdio-multiplexer@4c000 {

	compatible = "amlogic,g12a-mdio-mux";

	reg = <0x0 0x4c000 0x0 0xa4>;

	clocks = <&clkc CLKID_ETH_PHY>,

		 <&xtal>,

		 <&clkc CLKID_MPLL_5OM>;

	clock-names = "pclk", "clkin0", "clkin1";

	mdio-parent-bus = <&mdio0>;

	#address-cells = <1>;

	#size-cells = <0>;

	ext_mdio: mdio@0 {

		reg = <0>;

		#address-cells = <1>;

		#size-cells = <0>;

	};

	int_mdio: mdio@1 {

		reg = <1>;

		#address-cells = <1>;

		#size-cells = <0>;

		internal_ephy: ethernet-phy@8 {

			compatible = "ethernet-phy-id0180.3301",

				     "ethernet-phy-ieee802.3-c22";

			interrupts = <GIC_SPI 9 IRQ_TYPE_LEVEL_HIGH>;

			reg = <8>;

			max-speed = <100>;

		};

	};
